AUTOMOBILE ATTACHMENT Original Filed Feb. 16, 1927 /7 III I '5 I g A! "I'IIIII' Patented Aug. 12, 1930 PATENT OFFICE GUS MARENTI, OF WASHINGTON, DISTRICT OF COLUMBIA AUTOMOBILE ATTACHMENT Application filed February 16, 1927, Serial No. 168,595. Renewed March 15, 1930.

This invention relates to attachments for internal combustion engines and more particularly to a novel cleaning appliance for use in conjunction with automobiles.

One of the primary objects of the present.

invention is to provide a novel cleaning attachment comprising a portable base having means for permitting the connection thereof with an exhaust pipe of an automobile for creating a continuous suction in said base, the suction being utilized for various cleaning purposes.

Another salient feature of the invention is the provision of a novel cleaning attachment for automobiles comprising a chamber having an outlet at one end and an inlet at the opposite end, the outlet having a cleaning hose connected therewith and means for detachable connection with exhausts of automobiles leading into the outlet pipe for creating a suction in rear of the pipe, whereby water or other cleaning fluid will be drawn in through the inlet and commingled with the exhaust flowing through the outlet.

A further object of the invention is the provision of a novel cleaning device for automobiles comprising a box like structure to form a support having arranged therein a compartment provided with an inlet and outlet, the compartment also having means for connection with the exhaust of an automobile for leading the exhaust into the outlet pipe for creating a suction in rear thereof, the suction being utilized to draw in water or other cleaning fluid through the inlet, whereby the cleaning fluid can be expeditiously forced against the surface to be cleaned.

A further object of the invention is the provision of a novel cleaning hose connected with the outlet of the compartment, the nozzle of the hose being provided with an annular cleaning pad entirely surrounding the outlet end thereof, thereby permitting the nozzle of the hose to be used as a combined cleaner and scraper against the surface to be cleaned.

A further object of the invention is the provision of a cleaning attachment for automobiles which can be used not only as means for washing the vehicle, but also as a vacuum cleaner for permitting the convenient cleaning of the interior of the vehicle, the inlet of the compartment in this instance being used as a connection for the suction hose ofthe vacuum cleaner.

'A still further object of the invention is to provide a novel feeding attachment for automobiles of the above character, which will be durable and eflicient in use, one that willbe simple and easy to manufacture, and one which can be placed upon the market and incorporated with a conventional automobile at a small cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a side elevation of the improved cleaning attachment showing the same congelcted with the exhaust pipe of an automo- Figure 2 is a vertical longitudinal section through the base of the attachment,

Figure 3 is a transverse section through w the same taken on the line 33 of Figure 2 looking in the direction of the arrows,

Figure 4 is a perspective view showing a vacuum cleaner nozzle and pipe which can be used with the attachment, and

Figure 5 is .a detail side elevation of the cleaning nozzle showing the novel cleaning pad connected therewith, the pad being shown in section.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved attachment and B an automobile with which the same can be used.

The automobile B forms no part of the present invention and has been shown to illustrate the use of the attachment. As shown the vehicle B includes the usual body 10 having an exhaust pipe 11 leading to the rear end thereof.

'The improved attachment A comprises a base 15, which can be of any desired shape or size and provided with suitable handles or the like to facilitate the carrying thereof.

The base 15 is preferably of a hollow construction and the upper end thereof is provided with a horizontal partition 16 providing a compartment 17 which forms one of the salient features of the present invention.

one end of the compartment 17 is provided with a resgicted outlet pipe i8, whills the oppositeq i rmflad' ea 19. outer ends of the pipes 18 and 1 are preferably externally threaded for permitting the connectiua It hosetharetn'a as will be later described.

The outlet pi e 18 extends com. pertinent 17 an is provided with a flared inlet end or'ventufi Extending, from the base. 15 at an angle of A thirty degrees to the horizontal is eiuex'fiaust inletpipe 21. This pipe excases into the compartment 17' and terminates 'man injector noazle22, whichis disposed in clmapmximity tn'tha end. 20 of the outlehpipe I81 mentor and either pipefil 1's externally as. atflfl mthat abuse 24 can be therewith. This hose 24. is. arranged: for detachable. connection with the rearend of the exhaust pipe ILL v The outlet .18. isadapt'ed to. receive a fliazcible.cleaning osefllihavingany Eirseferred tygeoihnzzloflfi atitsouter end'.

In this instance the hose 25 is not used and it can be seen that the exhaust flowing into the outlet tube 18 will create a suction at the pipe 19. The suction nozzle 32 can be conveniently used for cleanfirs the interior of the car, such as the upstery thereof.

From the foregoing description it can be seenthat I have provlded a novel and simple attachment to be used. in connection with automobiles for facilitating the cleaning thereof.

While I have. shown the hose 24 connected withthe rear end of the exhaust pipe 11, of the automobile 10 it is to be understood that this hose can'be connected to the exhaust pipe 11 at any oint intermediate the ends thereof either in ront or in rear of the conventional mufller, by the use of suitable fittings, (not shown).

The nozzle 26 can be provided with a suitable covering formed of non-heat conducting material or a suitable handle of non-heat conducting material can be connected with the nozzle whereby the. hand of the user will be rotected from heat from the exhaust.

hanges in details ma be made without departing from the spirit or scope of this invention, but:

What I claim as new is:

A pump attachment for an internal com.- bustion engine for the urpose specified connprising a casing entire y independent of the engine forming a supporting body, a fluid inlet pipe at one end of the casing, 21 fluid outlet pipe at the opposite end'of the casing having an inner flared intake ortion and a connection for the exhaust of t e engine leading into the casing at an angle toward the outlet pipe between the inlet and outlet pipes and terminating in said flared intake portion in spaced relation to the walls thereof.

In testimony whereof I atfix my signature.
